Answer key A certain brand of car is rated to get 35 miles per gallon on the highway. A researcher believes the claim is faulty – that is too high. His company drives a random sample of 40 cars in identical highway conditions for a total of 500 miles and checks the fuel economy. He finds that the average rating for the cars is 32.54 miles per gallon. Using a population standard deviation of 1.3mpg, determine if there is evidence at the 2% level that the company’s claim of 35 mpg is too high. Also, find a 98% confidence interval for the average mileage rating of this car and interpret the answer.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
